1998 Hyundai Sonata
Fuel Economy Overview
The 1998 Hyundai Sonata achieves an EPA-estimated 18 MPG in combined city and highway driving, with 15 MPG in the city and 22 MPG on the highway. Powered by a 3L 6-cylinder engine paired with a automatic 4-spd, this midsize cars features Front-Wheel Drive drive.
In terms of environmental impact, the 1998 Sonata produces approximately 494 grams of CO2 per mile. This figure is measured under standardized EPA test conditions and represents tailpipe emissions only. For context, the average new vehicle sold in the United States produces approximately 400 grams of CO2 per mile, meaning this Sonata has higher-than-average emissions in this regard.
The estimated annual fuel cost for this vehicle is $3,300, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $5,750 over a 5-year period. This calculation accounts for differences in fuel consumption efficiency and provides a practical measure of long-term ownership costs attributable to fuel economy.

Personalized Commute CalculatorEPA defaults to 55% City / 45% Hwy
Adjust the slider to match your daily driving habits. City driving involves stop-and-go traffic under 45mph, while highway driving represents sustained speeds over 55mph.
Aerodynamic Speed Penalty
EPA highway tests average roughly 48 mph. Driving at 75 mph increases aerodynamic drag exponentially. Expect your real-world highway fuel economy to drop by roughly 15-20% at interstate speeds.

VEHICLE DESCRIPTION: ACCENT GT MODEL VEHICLES EQUIPPED WITH DOHC ENGINES MANUFACTURED FROM DECEMBER 19, 1996 THROUGH JUNE 30, 1997; 1998 ACCENT MODEL VEHICLES MANUFACTURED FROM MAY 6, 1997 THROUGH JUNE 25, 1998; 1997 SONATA VEHICLES MANUFACTURED FROM AUGUST 1, 1996 THROUGH JULY 9, 1997 AND 1998 SONATA VEHICLES PRODUCED FROM JULY 9, 1997 THROUGH APRIL 24, 1998. THE EVAPORATIVE EMISSION CONTROL SYSTEMS MAY APPLY EXCESSIVE VACUUM TO THE FUEL TANKS DURING THE CANISTER PURGE CYCLE. MINOR FUEL TANK DISTORTION COULD RESULT. A SMALL CRACK COULD DEVELOP ON THE UPPER FUEL TANK SURFACE. THE "CHECK ENGINE" LIGHT WOULD THEN ILLUMINATE AND, IN SOME CASES, THE VEHICLE DRIVER COULD NOTICE A GASOLINE ODOR.
Consequence & Remedy
Consequence: FUEL LEAKAGE IN THE PRESENCE OF AN IGNITION SOURCE CAN RESULT IN A FIRE.
Remedy: DEALERS WILL PRESSURE CHECK THE VEHICLE'S FUEL TANK TO DETERMINE IF IT HAS CRACKED. IF IT IS CRACKED, A NEW FUEL TANK WILL BE INSTALLED. A NEW FUEL FILLER CAP THAT DECREASES THE AMOUNT OF VACUUM INSIDE THE FUEL TANK WILL ALSO BE INSTALLED. NOTE: THE 1997-1998 SONATA FUEL TANKS HAVE ALSO EXPERIENCED CRACKING. HOWEVER, AT THIS TIME, THE CAUSE FOR THE CRACKING HAS NOT BEEN IDENTIFIED. THIS PORTION OF THE CAMPAIGN WILL BEGIN AFTER HYUNDAI HAS DETERMINED THE CAUSE AND CORRECTIVE PROCEDURE.
